In software revamp projects, the natural instinct is to dive straight into design and development. Especially if stakeholders already have a wishlist of features and a rough scope in mind, discovery can feel like a delay. But skipping this early phase is often what derails revamp projects in the first place.
The discovery phase isn’t about stretching timelines. It’s about making sure what you build is actually right and feasible.
What Exactly Is the Discovery Phase?
Discovery is like a blueprinting stage before construction.
It’s where teams evaluate the current system, gather inputs from real users, analyze business goals, and uncover technical roadblocks. All happens long before committing to a single line of code.
A typical discovery phase includes:
- Codebase assessment to identify potential risks and compatibility issues
- Stakeholder interviews to understand goals and constraints
- User research to validate pain points and map real user journeys
- Infrastructure review to assess scalability, security, and bottlenecks
- Success criteria definition to align teams on what “done right” looks like
This upfront work ensures your revamp effort doesn’t just look modern, but it works better, performs stronger, and supports future growth.
When Discovery Is Skipped: Challenges We’ve Seen Firsthand
Skipping discovery might seem like a shortcut. But it usually ends up costing more in time, money, and morale. Here are four of the most common issues we’ve seen when teams bypass this step, and how discovery helps avoid them:
1. Legacy code issues surface too late
Without a deep dive into the existing codebase, critical blockers like deprecated gems, tight coupling, or missing tests often emerge during development. These setbacks can derail timelines and create frustration.
What helps:
A thorough technical audit during discovery surfaces these risks early, so they can be scoped and prioritized before work begins.
2. Teams make assumptions about what needs fixing
Without structured input from users and stakeholders, teams often guess what to improve and miss the mark. Time gets spent on low-impact fixes while real pain points remain untouched.
What helps:
Discovery includes feedback loops that ground the revamp in real-world needs, not just assumptions.
3. Architecture gets over- or under-designed
Without clear scope and usage patterns, revamps tend to either over-engineer (driving up costs) or under-plan (creating technical debt).
What helps:
Discovery aligns your architecture plan with current and future needs, so it’s lean today and scalable tomorrow.
4. Rigid plans fall apart mid-execution
Projects that skip discovery often have brittle timelines. Once new information surfaces (and it always does), teams scramble to adjust.
What helps:
Discovery builds in flexibility. It anticipates what might change, outlines options, and ensures teams can pivot smoothly.
A Quick Story: Real Results from a Rails Discovery Done Right
One of our clients at Railsfactory, a well-established crowdfunding platform, came to us with a clear goal and it is modernizing the aging Rails app to better serve their rapidly growing user base.
Through a focused discovery phase, we collaborated closely with their team to deeply understand technical gaps, legacy blockers, and product goals. Our roadmap involved upgrading their Rails application from version 4.2 to 6.1, addressing deprecated dependencies, improving CI/CD pipelines, and reworking parts of their architecture to support scale.
Here’s what happened after launch:
- Page load times improved by 73%
- Platform availability rose to 96%, even during peak traffic
- Application performance tripled, enabling smoother user experiences and lower churn
All of this was made possible because the discovery phase revealed what truly mattered and where to focus. No guesswork. Just informed, strategic modernization.
What to Expect During a Discovery Phase
There’s no standard playbook for discovery. The depth and scope depend on your app’s complexity, age, and business context. But most discovery phases include:
- Technical assessments of code, infrastructure, and third-party integrations
- Risk mapping to surface known unknowns
- Backlog creation for the revamp or re-architecture effort
- Roadmap planning with cost, effort, and timeline estimates
By the end, teams walk away with clear documentation, priorities, and confidence to move forward or rethink the approach if needed.
Pro Tips for Making Discovery Work
If you’re planning to modernize in 2025, here are a few tips that help us (at RailsFactory) get the most out of the discovery process:
- Don’t treat it like a checkbox. Take your time.
- Get input from all the right teams from day one.
- Document everything. Yes, even the obvious stuff.
- Set realistic KPIs early so everyone knows what success looks like.
- Prioritize the tricky stuff upfront (outdated dependencies, legacy integrations, etc.).
Final Thought: It’s not a delay, it’s an investment
In today’s rush to release, teams often trade clarity for speed. In 2025, speed matters, but direction matters more.
Skipping discovery might look efficient, but it often leads to missteps, rework, and stalled momentum. A strong discovery phase helps you define what really matters, reduce uncertainty, and move forward with purpose.
Whether you’re revamping legacy systems or scaling for the future, discovery is how you build clarity into every decision.
